so for all practical purposes the 2.4 ghz is interfence free, now lets look at radios...the 6ch spektrum6ch is a great deal but no servos. Does it come with rx and tx batteries and charger. The 7ch spektrum comes with full nimh batteries a charger and 4 standatd servos according to a friend I fly with. It's about $150 more but you get $120 worth of servos. How does the airtronics compare?
